Router rebuild (or, an excuse to play with IPv6?)

So recently my router decided it didn’t want to whir its fans anymore and consequently gave up on life. It’s a dual CPU machine and both CPU fans had managed to wedge. After fixing them and getting things running again I heard klunking noises coming from the front of the case; one of the disks in the mirror had failed. …

The wonders of computer generated art

I’ve always been fascinated by computer generated art, in particular the landscape work. Over the past few years they seem to be getting so good that it’s often hard to tell the difference between them and real scenery photographs. The main site I visit is digitalblasphemy.com, and I pay the small subscription fee to get access to the latest images. …

Neat tool: bwm-ng

I recently found a neat little tool whilst looking for applications that link against libstatgrab. It’s called bwm-ng and is written by a guy called Volker Gropp. The tool itself isn’t anything revolutionary (it’s influenced by the original bwm tool), it’s just a handy way of displaying current bandwidth usage across multiple interfaces. This screenshot shows bwm-ng in action on my FreeBSD router. It has …

Where is the support for categories? So, moving …

Upgrading from FreeBSD 5.2 to 5.5 (RELENG_5)

I’ve been putting off upgrading my remotely hosted server from FreeBSD 5.2.1 for a while now, but after I started getting random problems I decided I had to move forward. To start with there were a few reasons putting me off doing the upgrade: From version 5.3 of FreeBSD vinum was pretty much broken, so I’d need to switch to …

My first post

So, yet another blog. Given that there are more bloggers than blog readers one might have thought another blog would be largely pointless. They’re probably right. However, my intention is not to write an uninteresting blog about what I saw on television last night, what colour the sky is on my planet, or whether I prefer my toast with or …
